what are feeder bands in a hurricane

Around 74 mph (119 km/h) the strong rotation of air around the cyclone balances inflow to the center, causing air to ascend about 10-20 miles (16-32 km) from the center forming the eyewall. Lower winds drag against land or water and thus spiral more tightly around the low an effect usually seen within an altitude of 5,000 feet.

The arc shaped feeder bands eventually move toward the storm's center, encircling it and producing the doughnut shaped "eye wall" which lends the hurricane its unique appearance on weather radar screens and satellite images. The area over which tropical storm-force winds occur is even greater, ranging as far out as almost 300 miles (483 km) from the eye of a large hurricane.

Produced by a cumulonimbus cloud, it is a microscale event of relatively short duration characterized by thunder, lightning, gusty surface winds, turbulence, hail, icing, precipitation, moderate to extreme up and downdrafts, and under the most severe conditions, tornadoes. In tropical cyclone, as the air moves toward the center, the speed must increase.
